PILE-SHOE.

SPECIFICATION forming part of Letters Patent No. 744,256, dated November 17', 1903. Application filed July 6, 1903. Serial No. 164,264. (No model.)

To all whom it may concern: 1

Be it known that I, JOSEPH A. STEINMETZ, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Pile-Shoes, of which the following is a specification.

This invention relates to an improved shoe for protecting the point of a pile and facilitating the penetration thereof. Its chief object is to provide a shoe for effecting an improved engagement With the pile to facilitate penetration and prevent the point from splitting or brooming.

The nature and characteristic features 0 the improvements will more fully appear by reference to the following description and the accompanying drawings in illustration thereof, of which- Figure l-represents an elevation of the point of a pile having my improved shoe applied thereto. Fig. 2 represents a vertical sectional view of the construction shown in elevation in Fig. 1. Fig. 3 represents a vertical sec; tional View showing a modification of the con struction illustrated in Fig. 1. Fig. 4 repre sents a top plan view of a shoe having a rectangular section made in accordance with my invention. Fig. 5 represents a top plan view of a shoe having a circular section made in accordance with myinvention. Fig. 6 represents a top plan view of a shoe having a hexagonal section made in' accordance with my invention. Fig. 7 represents a sectional view of a preferred connection between'the shoe and its strap. Fig. 8 represents a perspective View of a section of tie-strap buckled for insertion in its seat in the pile, and Fig. 9 represents a sectional view of the buckled tiestrap placed in its seat in the shoe.

Referring to the drawings, the shoe 1 is provided with an unbroken flat-bottomed socket 2 and has the seats or channels 3, preferably having a dovetail cross-section and depressions 4. and 5. The socket 2 receives and binds the point 6 of the pile. The seats or grooves 3 receive the endsof the tie-straps 7, which may be buckled and inserted, as shown in Figs. 8 and 9, to be hammered or compressed into conformation with the seat and indented to engage the depressions 4 and 5 thereof. An engagement may also be effected by passing rivets 8 through the straps and socket-Walls. The straps are secured to the pile-point by nails 9.

.There is thus provided a shoe having means for readily connecting it in firm engagement with' the point of thepile and maintaining it in alinement for efiecting penetration with the minimum resistance.

Having described my invention, I claim- 1. A pile-shoe having an unbroken fiat-bottom socket for seating a pile-point, and means for engaging a strap to said socket, substantially as specified. 2. A pile-shoe having dovetailed channels therein and straps compressed in said chan- I nels, substantiallyas specified.

3. A pile-shoe having a flat-bottomed socket 'forseating a pile-point, straps for engaging said pile-point, and dovetailed channels in said shoe in which said straps are compressed, substantially as specified.

4. A pile-shoe having a groove therein, a

depression in said groove, and a' strap set in said groove and depression, substantially as specified.

In testimonywhereof I have hereunto set my hand, this 3d day of July, A. D. 1903, in the presence of the subscribing witnesses.

JOSEPH A. STEINMETZ.
